Based on the recording and playback configuration information preset by the user, the controller can execute the playback of the clips in the live program process. Fig. 7 is a flowchart of a first program playback method provided in some embodiments of the present application, which may be executed by the controller 250, including the following steps:

step S71, play the first program.

In some embodiments, the first program is started, including but not limited to the following: the user can start the display device and the signal source device (such as a set top box and the like), and after entering a TV signal source, the user defaults to start the live broadcast of the program of the current channel and the current playing period; the user can also switch channels (i.e. switch channels) to start live broadcasting programs of other channels in the same playing period; or after the live broadcast of the program A of the current channel is finished, automatically jumping to the live broadcast of the next program of the same channel.

Step S72, acquire the recording and playback configuration information previously set by the user.

The manner in which the recording and playback configuration information is preset by the user may refer to the description of the foregoing embodiments, which is not repeated here.

Step S73, determining whether the first program and the recorded program information match.

The purpose of executing step S73 is to: it is determined whether the first program currently being played is a program that meets user viewing preferences that may be attractive to the user to play back the clip during live. The controller may acquire information (hereinafter referred to as first program information) of a channel to which the first program belongs, a program type, a program name, a program playing period, etc., and compare the first program information with recorded program information preset by a user.

The first program information corresponds to an information set a, the recorded program information corresponds to an information set B, and if the information set B is an empty set, or the information set B is a non-empty set and the information set a does not include the information set B, it is considered that the first program and the recorded program information do not match, step S74 is performed. For example, the first program information is a live tennis tournament broadcast by CCTV5 in the period 14:00-14:40, and the information set a may be exemplified by { belonging to the channel: CCTV5; program type: sports programs; program name: live tennis tournaments; program play period: 14:00-14:40 }, when the user presets the recorded program information, setting the news to be recorded and played back CCTV1, i.e. the information set B is { belonging to the channel: CCTV1; program type: news program }, it is apparent that the information set a does not contain the information set B, and it is determined that the first program information and the recorded program information do not match.

If information set B is a non-empty subset of information set A, the first program is considered to match the recorded program information, step S75 is performed. For example, the first program information is an track and field tournament live broadcast by CCTV5 in 09:30-10:30 period, then the information set a may be exemplified by { belonging to the channel: CCTV5; program type: sports programs; program name: live broadcast of track and field tournaments; program play period: 09:30-10:30 }, when the user presets the recorded program information, the user sets the sports program to be recorded and played back, i.e. the information set B is { program type: sports program }, it is apparent that information set B is not empty and information set B is a subset of information set a, then it is determined that the first program information matches the recorded program information.

Step S74, the first program is continuously played.

In some embodiments, if the first program does not match the recorded program information, indicating that the first program does not meet the recording and playback conditions specified by the user, the display device continues to live the first program, including: the controller controls the audio player to continue playing the audio of the first program, and controls the display to continue displaying the video of the first program. The audio player may be a speaker built in the display device, or may be an external playing device (e.g. sound equipment, bluetooth earphone, etc.).

Step S75, playing and recording the first program.

If the first program matches the recorded program information, it is indicated that the first program is a program that meets the user's viewing preferences and that may entice the user to play back the segment during live. The display device may be configured with modules and hardware interfaces such as a LiveTV module, a recording module (Record), a signal source interface (e.g., HDMI), an interface for connecting an external storage device (e.g., USB), etc., wherein the LiveTV module may receive a program signal and a code stream from the signal source interface; the recording module is used for recording the program code stream in a preset storage path (for example, a memory built in the display device or an external storage device) according to a specified format (for example, avi format, mp4 format and the like). By recording the program matching the recorded program information, playback of any segment of the first program can be facilitated.

Step S76, receiving a first playback operation input by the user during the playing of the first program.

In some embodiments, a playback key may be set on the control apparatus 100, and if the user clicks the playback key during live broadcasting of the program, the control apparatus 100 sends a first operation instruction including a key value of the playback key to the display device; the display device receives the first operation instruction, analyzes the key value included in the first operation instruction, and determines that the first playback operation is received when the key value mapping playback key is identified, so that the one-key quick playback of the program fragment is realized. The embodiment of the application refers to a playback operation received by the display device when a program is live as a first playback operation.

In some embodiments, if the display device has a voice control function, the user may trigger playback of the program segment through a voice command, for example, the user speaks "playback" into the microphone device, and the display device converts the audio into text "playback" by performing voice processing on the audio information, which may identify that the user intends to play back the program segment, which is equivalent to receiving the first playback operation.

In some embodiments, a playback control may be disposed on the program play interface, and the display device receives the first playback operation when the user clicks the playback control.

In some embodiments, if the display device supports gesture control, the user may preset a playback gesture for playing back the program segment when the program is live, so that when the user makes a gesture, the display device may identify the gesture, and if it identifies the gesture as the playback gesture, it is equivalent to receiving the first playback operation. Note that, the input manner of the first playback operation is not limited to the example of the present application.

Step S77, determining a first playback starting position according to the current playing progress of the first program and the preset playback time length.

In step S78, the first program segment is played at the first playback start position.

Fig. 8 is a schematic diagram of positioning a playback start position according to some embodiments of the present application. Referring to fig. 8, on the playback time axis of the first program, it is assumed that the current time is T _now ，T _now On the left is the elapsed history time, T _now To the right is the future time that has not yet been experienced, T _now Rollback preset playback duration t _y After a time period of (2), a playback start position T can be obtained _h T, i.e _h ＝T _now -t _y . In the embodiment of the application, the playback start position located when the first program is live is simply referred to as the first playback start position T _h1 。

In this way, the display device can receive the first playback operation from the playback start position T _h The program segments are played. Wherein the first program segment is according to a first playback start position T _h1 And a preset playback time period t _y A section taken from the media data of the first program recorded previously, the playing section of the first program section being (T _h1 ,T _h1 +t _y ) I.e. the duration of the first program segment is equal to the preset playback duration t _y 。

In some embodiments, when the controller receives the playback operation during the live program, the controller may obtain the video frame currently played by the first program (hereinafter referred to as the first video frame) and obtain the pts of the first video frame (Presentation Time Stamp, displayTime stamp). The controller rolls back the first display time stamp along the play time axis of the first program by a preset playback time period t according to the principle of the example of fig. 8 according to the display time stamp of the first video frame (hereinafter referred to as the first display time stamp) and the preset playback time period _y And thereby a second display time stamp corresponding to the playback start position. In this way, the controller may intercept and play back the first program segment based on the first display timestamp and the second display timestamp.

In some embodiments, assume that the first program is currently on for a time period t ₁ When the controller receives the first playback operation, the controller calculates a playback start position T by using a rollback mechanism on a program playing time axis _h The playback start position T _h Can be used for representing playback starting point and program starting point t ₀ The length of time before, i.e. T _h Can be equal to t ₁ -t _y If the user's viewing period is short after the first program is started, a first playback operation is entered, t may occur ₁ Less than t _y In this way, the playback start position T is theoretically calculated _h Is negative, i.e. the playback start point is located at the play-start point t of the current program ₀ Previously, a program equivalent to a jump to the previous program may result in a failure to play back a clip or a false playback. Thus, when the controller locates the playback start position, if t is detected ₁ Less than t _y The playback start position T can be set _h Positioning to the program start-play point t ₀ I.e. from the program start point t ₀ The first program segment is played back. The duration of the first program segment intercepted in the scene may be t ₁ I.e. the playing interval of the first program segment is (t ₀ ,t ₀ +t ₁ ) The method comprises the steps of carrying out a first treatment on the surface of the Alternatively, the length of the intercepted first program segment is still t _y The playing interval of the first program segment is (t ₀ ,t ₀ +t _y )。

Fig. 9 is a flowchart of a second program playback method provided in some embodiments of the present application, and referring to fig. 9, the method may be executed by the controller 250, and includes the following steps:

Step S91, playing the first program.

Step S92, acquire the recording and playback configuration information set by the user in advance.

Step S93, determining whether the first program and the recorded program information match.

If the first program does not match the recorded program information, then step S94 is performed; if the first program matches the recorded program information, step S95 is performed.

Step S94, the first program is continuously played.

Step S95, playing and recording the first program.

Step S96, a first playback operation input by a user is received.

Step S97, detecting whether the second program currently being played matches the recorded program information.

In some embodiments, the controller may switch channels from program a of channel a (the first program) to program B of channel B (the second program) before receiving the first playback operation; or when the live broadcasting of the program a of the channel A is finished, automatically switching to the program b broadcasted in the next period of the same channel A. Since the timing of the user's input of the first playback operation is not fixed and cannot be predicted, the display device may still play the first program or have been switched to other programs when the controller receives the first playback operation.

In this embodiment, the second program is a program that is being played by the display device when the first playback operation is received, and the second program may be the same or different from the first program, so that in order to accurately identify whether the segment of the second program can be played back, the controller needs to detect the matching between the second program and the recorded program information, and the description about step S73 may be specifically omitted here. If the second program is not matched with the recorded program information, executing step S98; if the second program matches the recorded program information, step S99 is performed.

Step S98, displaying the first prompt information on the upper layer of the playing interface of the second program.

Fig. 10 is a schematic diagram of a first prompt message provided in some embodiments of the present application. If the second program does not match the recorded program information, referring to fig. 10, the controller may control the display to display the first prompting information 101 on the upper layer of the playing interface of the second program, where the first prompting information 101 is used to prompt that the second program does not support the recording and playback function, and prompt the user to modify the recording and playback configuration information (including the recorded program information) on the system setup page. The first hint information 101 is illustrated in fig. 10 as "the current program is not a program meeting the recording and playback conditions, and if you want to play back a highlight in the program, you first set the recording and playback options in the system settings".

Fig. 11 is a schematic diagram of a first prompt pop-up window according to some embodiments of the present application. If the second program does not match the recorded program information, referring to fig. 11, the controller may control the display to display a first prompt pop-up window 111 on an upper layer of a playing interface of the second program, where the first prompt pop-up window 111 may include a second prompt message 111a, an immediate setting control 111b, and a closing control 111c. The second prompting message 111a is used for prompting that the second program does not support the recording and playback function, and asking the user whether to immediately modify the recording and playback configuration information.

In some embodiments, the controller controls the display to close the first prompt pop-up 111 and jump to the record and playback setting sub-page in response to the user clicking the immediate setting control 111b, so that the user can adjust the recorded program information in the first tile 51 to match the adjusted recorded program information with the second program. The controller responds to the operation of clicking the closing control 111c by a user, controls the display of the first prompt popup window 111, and records and plays back configuration information unchanged.

Step S99, determining a second playback starting position according to the current playing progress and the preset playback time length of the second program.

Step S910 plays the previously recorded second program segment at the second playback start position.

If the second program matches the recorded program information, it indicates that the second program was synchronously recorded when the second program was previously played, so that the controller can locate the second playback start position T when receiving the first playback operation entered by the user _h2 And from the second playback start position T _h2 The second program segment is played back. Wherein the second playback start position T _h2 Is a playback start position positioned when the second program is live, a second playback start position T _h2 The positioning method of (a) can refer to the first playback start position T provided in the related embodiment of the step S77 _h1 The positioning method of (2) is not described herein.

In this embodiment, the second program segment is based on the second playback start position T _h2 And a preset playback time period t _y A section taken from media data of a previously recorded second program, a play section of the second program section being (T _h2 ,T _h2 +t _y ) I.e. the duration of the second program segment is equal to the preset playback duration t _y . In this way, when the controller receives the first playback operation, the controller identifies the feasibility of playback of the program segment by secondarily detecting the matching between the currently on-air program and the recording and playback configuration information, prompts the user if the program segment cannot be played back, and plays the program segment after locating the playback start position if the program segment can be played back.

In some embodiments, when the display device plays back the target program segment of the current program, if the controller detects that the playing of the target program segment is finished, a second video frame may be acquired, where the second video frame is a video frame that has been played back by the current program when the playing of the target program segment is finished, and it is assumed that the playing of the target program segment is finished at time t _S Then t _S -(T _h +t _y ) Not less than t _y The controller may control the display to continue displaying the video of the current program (including the second video frame) from the display timestamp corresponding to the second video frame, and control the audio player to continue playing the audio of the current program, so that the segment playback is automatically aligned to the real live progress of the current program after the segment playback is finished. The current program may be a first program, a second program or other programs in the embodiments of the present application, and the target program segment may be any segment in the current program that the user desires to review (for example, a first program segment in the first program, or a second program segment in the second program, etc.).

In some embodiments, the display device may, when playing back the target program segment of the current program, if it detects that the playing of the target program segment is finished, select from T _h +t _y And continuing to play the audio and video contents after the current program at the time node. The method can avoid that the user loses that the current program is truly played during the playback of the clips and is not smaller than the preset playback time t _y The integrity of the program playing is ensured, but the playback of the segment is not aligned with the real live broadcast progress of the current program, that is, the playing hysteresis is generated, and the program progress after continuous playing lags the real live broadcast progress.

Fig. 12 is a flowchart of a method for saving a program recording file at the end of live broadcasting of a program according to some embodiments of the present application. Referring to fig. 12, the method may be performed by the controller 250, including the steps of:

step S121, detecting the matching between the third program and the recorded program information when the live broadcast of the third program currently being played is completed.

The third program may be the first program, the second program, or other programs in the embodiments of the present application. The program live broadcast end includes the following three cases:

in the first case, under the condition of no channel cutting, the playing of the program A in the current period is finished, and the program A automatically jumps to the program B in the next period of the same channel;

In the second case, in the channel switching scene, switching from the program A of the channel 1 to the program C being played by the channel 2 in the current period; the program played by the display device changes in both the first case and the second case.

In case three, the controller receives an operation from the user to close the program playing interface, where the operation may include, but is not limited to: the user switches the source (e.g., exits the TV source, switches to an application M), turns off the source device (e.g., set top box, etc.), turns off the screen or turns off the screen, clicks a home button on the control device 100, etc.

Step S122, determining whether the third program matches the recorded program information.

If the third program does not match the recorded program information, then step S123 is performed; if the third program matches the recorded program information, step S124 is performed.

Step S123, stop playing the third program.

When the third program does not match the recorded program information preset by the user, the third program is not synchronously recorded when the third program is played first, so that the display equipment does not have or can not store the program recorded file of the third program, and live broadcast of the third program can be ended.

Step S124, stopping playing and recording the third program, and obtaining the storage mode information.

When the third program matches with the recording program information preset by the user, it indicates that the third program is synchronously recorded when the third program is played first, so that the user plays back any segment during the live broadcast of the program, and thus the controller can end the live broadcast of the third program, stop recording the third program, and acquire the storage mode information from the recording and playback configuration information preset by the user, where the storage mode information is used for indicating whether to store the program recording file.

Step S125, determining whether to save the program recording file.

If the saving mode information indicates that the program recording file is not saved, step S126 is performed; if the saving mode information indicates that the program recording file is saved, steps S127 to S129 are performed.

Step S126, deleting the program recording file of the third program.

Step S127, the program recording file of the third program is saved to the preset memory.

If the user presets to save the program recording file when the live broadcast of the program is finished, in step S127, the controller saves the program recording file to a preset memory, where the preset memory may be a built-in memory of the display device or an external storage device (for example, a usb disk, a mobile hard disk, etc.). If the user presets that the program recording file is not saved at the end of the live broadcast of the program, the controller deletes the program recording file and does not save the program recording file to a preset memory.

In step S128, in response to the second playback operation input by the user, the program recording file of the third program is read from the preset memory.

In step S129, the media player is started to play the program recording file of the third program.

The embodiment of the application refers to the operation of playing back the program recorded file of any program a, which is received by the display device after the live broadcast of the program a is finished, simply as a second playback operation. The controller receives a first playback operation and executes fragment positioning and playback logic during program live broadcasting; and the controller receives the second playback operation, executes the whole playback logic after the program live broadcast is finished, namely reads the target program recording file matched with the program information from the preset memory, and plays the target program recording file. Therefore, the embodiment of the application can realize playback of any designated segment during program live broadcast and playback of the complete program recorded file after the program live broadcast is finished, so that a user can repeatedly review interested program content for many times, and user experience is improved.
